IMPROVEMENT IN MOWERS.

Specification forming part of Letters Patent No. 193,697, dated July 31,1877; application filed May 5, 1877.

To all whom it may concern:

Be it known that I, WILLIAM W. EDGAR- TON, of Bouckville, in the countyof Madison and State of N ew York, have invented a new and usefulImprovement in Harvesters, of which the following is a full, clear, andexact description This invention relates more especially to amowing-machine such as described in United States Letters Patent No.121,784, granted to Harvey L. Hopkins, December 12, 1871.

In practice it was found that the swiveljoint provided for the rockingof the cutting apparatus was not sufficiently flexible to admit 0f thefolding or turning up of such cutting apparatus without severe strain onthe joints, unless they were made too loose for practical Work, and itwas almost an absolute necessity to tilt the cutting apparatus forwardby rocking the swiveling-bolt before it could be folded.

To remedy these difficulties I have improved the mechanism by theintroduction of a universal joint between the arm orcouplingarm of thecutting apparatus and the swiveling-bolt through which the cuttingapparatus is rocked.

In the annexed drawings, Figure 1 is a sectional elevation of part of aharvester. Figs. 2 and 3 are detail perspective views in illustration ofmy invention.

The same letters of reference indicate lik parts in all the figures.

A refers to the stiff arm or coupling-arm by which the cutting apparatusis connected to the swiveling-bolt B,which turns in a bearing of theframe O,its axis being in line with said ous rocking of the cuttingapparatus, I connect the swiveling-bolt and the coupling-arm by auniversal joint, formed, in this example, by the box Fturning onalongitudinal axis in the fork of the swiveling-bolt, and by transversejournals connected to the fork of the coupling-arm, as clearly'shown; v

It is obvious that the construction of the" universal joint may bemodified Without a departure from the principle of my invention.

7 What I claim as my invention, and desire to secure by Letters Patent,is-- The combination, substantially as specified, of the coupling-arm ofthe cutting apparatus, the swiveling-bolt arranged in line therewith,the lever controlling said bolt, and the universal joint intermediatebetween the coupling-arm and the swiveling-bolt.

In testimony whereof I have signed my name to the foregoingspecification in the presence of two subscribing witnesses.

WM. W. EDGARTON.
